hi , before i buy GravityForm i have question about input mask and how could we limit characters or allow only special characters and numbers for field
cause i read this : https://docs.gravityforms.com/input-mask/
and it seems input mask have only some “a” and “9” functions that use for create postal code or global phone numbers
what if i want more ? is Gravity Form support it ?
i want to have filed that user can input website url or only accept email
for sample only can input telegram channel link like this : https://t.me/****
